I This invention relates to refrigerated display cases and particularly to the method of refrigerating by ice and brine method.

An object of the invention is to provide a device of the character referred to that utilizes not only the ice and brine containers, for refrigerating a show case or other storage compartment, but makes use of the refrigeration produced from the drainage pipes that '10 carry the brine solution away from the container.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a device of the character referred to, that is 1 strong, compact, and durable, thoroughly reliable for its intended purpose, producing perfect refrigeration without dehydrating the storage compartment, that is very attractive in appearance, that is very simple 2 in its operation, and economic in assembly and that is comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of a novel con- 2.5 struction, combination and arrangement of characters designate like parts corresponding throughout the several views I Figure 1 is a front elevation of a show case in which the present invention is installed,

Fig. 2 is a rear elevation thereof,

Fig. 3 is a detailed, vertical longitudinal section therethrough,

Fig. 1 is a transverse vertical section in w detail, taken substantially on line 44 of Fig. 5 is a vertical, transverse, detailed section, taken substantially on the line 55 of Fig. 2 and looking in the direction of the arrows. 7

Referring to the drawings in detail, 6 rep resents a conventional built-in counter, upon which the show case of the present invention rests so as to be a height from the floor to permit easy vision by the prospective buyer. The display case, in accordance with the present invention is constructed on a base indicated generally at 7 and rests upon the counter 6.

At each end of the base 7 there are formed chambers 8, 9 and extending between these two chambers is a refrigerated storage compartment indicated generally at 10. The base 7 forms a continuous bottom for chambers 8 and 9 at the storage compartment 10, and is substantially flat 011 its upper and lower face.

This base 7 is rectangular in configuration and formed with vertically spaced sheet boards 11, 12 spaced apart by spacer blocks at intervals throughout its length. Of course the ends and side walls are closed by sheathing 14. Between the sheathing boards 11, 12 is a layer 15 of cork insulating and superimposed on the upper sheathing boards 12, is a layer of paper 16 upon, which rests a ply of felt 17.

Rising perpendicularly from the base 7 at its opposite ends, are the four walls of the chambers 8, 9. In horizontal section, the chambers are substantially rectangular and are formed with an open top. As aforementioned, the base 7 forms the bottom wall of the chambers 8, 9. The chambers 8, 9 are each formed in the same manner, and it is believed that a description of the one, will teach a clear understanding of the other. 8

Interiorly of the upstanding walls of the chamber there is a substantially rectangular space 18, the purpose of which will present- 1y appear. Each of the four walls of both chambers are formed on the outside with 99 sheathing boards 19 spacing from the inner sheathing board 20 and in the spaces between the sheathing boards is attached a rela tively thick course of insulating corks 21. Next to the inner sheathing board is secured a layer of heavy fiber 22 which is held in place by a metal sheathing 23.

The outer sheathing boards 19 project above the upper edges of the inner sheathr ingboards 20 so as to extend to and be seally at and includes an integral upwardly inclining rectangular frame 37, in wh1ch1s of the cover plate 25, that closes the upper ends of the upstanding walls. I-Iingedly mounted on the cover plate 25 as at 26, are

lids 27 properly insulated that close the upper ends of the space 18 between the walls of each chamber. i

A portion of the rear wall R of the storage compartment 10 is solid and vertically disposed. This solid portion of the rear wall 7 includes upstanding, transversely spaced inner and outer sheathing boards 30,, 31, the bottom edges ofwhich are secured to the base 7. The sheathing boards are co-extensive with the length of the compartments 10 and have a layer of cords 32 between and to form a proper insulation.

Supported on upper edges of the sheathing board as at 33, and sealing the top thereof, rests the lower edges of a Wooden frame indicated generally at34. A cross sectional area of theframe 34 will clearly appear from Fig. 5 of the drawings. A space within this frame 34providesa storage'compartment 36. The ends of the frame"34 are secured in ab-uting relation to the inner walls of the respective chambers, 8, 9 whereby the inner walls are continuous with the ends of compartments 36.

'It will therefore be apparent that some refrigeration will be produced by these inner walls that form the ends of the compartment. The front of the frame 34 is indicated genersupported three, spaced'plies of glass 38 that not only provide a proper insulation from the front of the compartment 10, but also permit vision of the customer into the compartment. Integral with the front frame 37 is the top frame 39 that is horizontally d1s- I posed and supported thereon are three spaced panels of glass 40. The frame 39 and the glass40 form the top wall of compartment 36.

The rear wall of frame 34 is provided with a plurality of openings 41, that are closed by the door frames 42 that are hingedly connected-as at 43 to the rear edge of the top frame 39. v V

Disposed across the door frames 42, are three, spaced plies or'glass panels 44, which permit vision into'the'compartment36 and also provide proper insulation. Any number of doors may be provided, depending" 'upon the length of thestorage compartment 36 and the size of articles to be stored therein. The frame 34 with the glass panels and the shortwall formed by sheathing boards 30 and 31, provide the sides of the refrigerating compartment .36.

Supported in each of the chambers 8, 9 are detall hereln any particular form, structure,

' upper face of the base 7 to provide a space for an elongated drip pan, 4? to extend through out the length of both chambers and the storage compartment 36.

The drip pan 4'? tapers slightly from each end toward the center and depending therefrom is a drain pipe 48 extending through the base 7, and into the proper drain. As best seen in Figure 4, the pan 47 terminates in enlarged end portions which are disposed beneath the containers 44 and 45. This drip pan 47 carries away condensation from the containers 44, 45, and the brine pipes to be presently described.

Extending throughout the entire length of the storage compartment 36, are a plurality of pipes 49 preferably vertically spaced and having a; very slightinclination toward the center of compartment 36 from each end. One end of the plurality'of pipes 49 is connected by a suitable fitting 50, to container 44, while the opposite ends of each plurality of pipes are connected by suitable fittings 51 to the container 45. Y

These plurality of spaced pipes 49 are preferably disposed toward the rear of the container and the lowermost one of the pipes projects through each container substantially flush with the bottom walls 46. The other pipes of the plurality are stepped above the lowermost one in a vertical plane, so as to carry the brine at various levels from the containers. v

In the center, the plurality of containers are connected with, in any suitable manner, a single tubular trap 52, that has a conductor 53 leading from its bottom wall into the drip pan 4?. In the event the trap 52 would be come clogged, or frozen, there leads from the displayed therein for sale will not only be attractive to the customer, but will be kept in a state of preservation.

The presentembodiment of the invent-ion has. been disclosed in considerable detail merely for the purpose of exemplification since in actual practice,'it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. 1 i

It is to be. understood that by describing in or arrangement, it is not intended tolimit the invention beyondthe terms of the several claims, or the requirements of the prior art.
